1. Remove all parts from their packing materials and retain the packaging in case you need to transport the

product.

2. Connect the power cord to a suitable power supply.

3.1 Basic Operation

1. Illumination controls, see figure 3

1.1. The power switch and transmitted / reflection

illumination toggle switch are located on the base. The

brightness control is located on the chassis. The

electrical system is fuse protected and the fuse holder

located on the power Inlet.

1.2. Press the power switch on the side of “I”, which

means the circuits is got through. If the light does not

appear to be ON, check the brightness control to see if

it’s on a sufficiently low setting. Then adjust the

brightness control until image can be observed

comfortably.

1.3. Note: Using the light at brightest setting will reduce

life span of bulb.

STEINDORFF®

2. Focusing Controls, see figure 3

2.1. Focusing adjustment: Is accomplished by using the large coarse adjustment knobs located comfortably

on each side of the frame. Fine adjustment is accomplished using the smaller knobs located on the same

focus shaft. This coaxial arrangement allows for easy, precise adjustment without drift or discomfort.

2.2. Focus Control: Turning either of the coarse focus control knobs will raise or lower the stage. The smallest

graduation on the fine adjust knob index scale is 2μm of vertical.

2.3. Focus Tension Adjustment: The tension of the coarse focus is adjustable and preset at the factory for

ease of use. If you wish to adjust the coarse focus tension, first locate the tension adjustment ring. Turning

the ring toward the front of the microscope increases the tension, and toward the rear of the microscope

loosens it. Tension is too high if you experience physical discomfort.

2.4. Pre-focusing or Focus Stop Control: Use of this feature will insure that the short working distance

objectives don’t contact the stage or slide glass when using the microscope. Its use also simplifies

focusing. After focusing on the slide glass with the coarse adjustment, rotation of the lever toward the rear

of the microscope will set an upper limit on the coarse adjustment movement. After changing slide glass or

objectives, focusing is easily accomplished by rotating the coarse adjustment knob to reach the pre-

focused position, then making fine adjustments with the fine adjustment knob. Focusing movement with

the fine adjustment isn’t affected by using the pre-focusing lever.

3. Diopter and Interpupillary Adjustments

3.1. Diopter Adjustment Proper correction for

individual vision is accomplished via the diopter

adjustment located at the left eyepiece. Using the

10X objective, bring an image into focus with your

right eye only. Once the image is well focused,

observe with left eye, make fine adjustments with

the diopter adjustment ring to correct for your

vision.

3.2. Proper interpupillary distance, or the distance

between eyepieces, is crucial to the comfort of the

user. Adjusting the interpupillary distance is

accomplished through a “folding” action of the

optical head, at Figure 4, allowing for quick and

easy adjustment.

4. Rotatable Stage Controls, see Figure 5

4.1. Put a specimen on the stage, observe it using dividing

eyepiece and 10X objective.

4.2. Search one target in field of view, adjust it to the center

of view. See Figure 6 A.

4.3. Rotate the stage. If the stage out of center, the target

will encircle the center of circle. See Figure 6 B.

4.4. To center the center of circle in the field of view. Use

the two centering screws, the stage centering adjustment

can be finished. See Figure 6 C.

4.5. If other objectives out of center, you may adjust it using

the objective centering screws.

4.6. Tightening the stage setting screw can fix the rotatable

stage.

5. Condenser Alignment Controls.

5.1. Condenser Components: The condenser is located

below the stage, see Figure 7. Abbe condenser; its

mounting ring with lock screw and two large centering

screws at either side. The adjustment knob for raising

and lowering the condenser.

5.2. Condenser Alignment – to center the abbe condenser

in the optical light path. See Figure 8.

a. Turn the 10X objective to optics path, close iris

diaphragm and lower the Abbe condenser until

observe the image of iris diaphragm.

b. If the Abbe condenser optics axis offset optics

system axis, the image of iris diaphragm is similar

to figure 8A. The image may be out of focus and

out of center.

c. Adjust the sub-stage adjustment knob until the side

of image is clear. Adjust the Abbe condenser

centering screw until the iris diaphragm locate in

the center of field of view, see figure 8 B.

d. Open the iris diaphragm until the image is almost

as large as the field of view, see figure 8 C. Raise

Abbe condenser again for normal observe.
